It appears that meshes do not adhere to the color set for locked objects.
In this screen shot, both the NURBS box and the mesh are locked and should therefore be displayed in the same color…
I’m not seeing the same here with the latest build of the day. Let me know if it still seems wrong after the next WIP release please.
Ha, well, yes. But that’s cheating 
Looks like some wires got crossed behind the scenes. Now also tested with the latest WIP.
Thanks for clarifying… filed as
